SPRTNG-TIRE FOR VEHICLE-WHEELS.

Specification oi Letters Patent. Ap lication 'filed May 31, 1911.

Sam No. 630,286..

To all whom it may concern:

Be it'known'that I-, Mom'm) E, COURT- NEY, a citizen of the United States, residing at Fair Play, in the county of Polk and State of Missouri, have invented newand useful Improvements in Spring-Tires" for Vehiole-VVheels, of'which the fpllowing is a specification.

This invention relates to improvements in spring tires tori vehicle wheels, and has for I an. object to provide a tire which will be extremely resilient or elastic, andwhich, in

- practice, will be found an'eilicient substitute for the well known pneumatic or rubber cushion tires.

' Another. object of the invention is to provide a tire which can be convenient y con-v nected with or disconnected from the telly of the wheel.

In the drawing, forming a; portion of this specification and in which like numerals of reference indicate "Fig. 2 is a transverse secshowing its application trating'the' threaded inner Walls of the cylindrical sockets,

My improved tire. comprises an outer I split ring .member 1 and a similar inner member 2, the terminals of each ring being provided with flanges 3 which are engaged y a fastening device-4. From this. construction it will be seen that the members 1 and 2 can be quickly and very, conveniently connected with or disconnected from the telly 5 of the wheel 6. The felly 5 is prefer ably provided with a transversely curved inner surface 7, and as illustrated, the inner ring member 2 ofthe tire is correspondingly curved transversely so as to present an inner convex surface to snugly fit in the concavity'in the outer surface of the telly and thereby prevent lateral displacementwof the inner ring member, onthe telly as will be understood.

The inner ring member is provided-with a series of radial studs-8 which are disposed in line withinwa'rdly extending radialsockets 9 on the outer ring member 1'. Strong members 1 and 2,

the ring members similar parts in the several'v1ews:-F1gure 1 1s a slde view of my improve Fig. 3 1s asection I Patented July 2, 191 2.

helical extensile spring's 10 are disposed radially with respect. to the telly 5, being interposed between'the innerand outer ring and as shown, the springs embracing .relation upon are arranged in held thereby against accithe studs 8 and dental displacement. wound-portions of the springslO, in effect, form screw-threads. The sockets 9 are threaded interiorly, at 11, so as to threadedly' receive the convolutions of the springs adjacent to the outer endsthereof. From this construction it will be readily seen that 1 and-2 can be quickly engaged with or disengaged from the telly 5 and when operatively mounted thereon, as shownin Fig. 20f the drawing, and connectedby the-springs 10, form an efficient substitute for the pneumatic or' solid cushion' rubber tire. preferably provided with an annularchannel 12 in which is fitted a cushioning surface 13 which may be constructed of rubber, leather or the like.

. I claim:

A tire comprising spaced innemand outer concentric split rings, springs iriterpbsed The convolutions or The outer ring member. is f of integrally formed inwardly extending the said'outer split concentric ring being provided with a series of integrally formed --ihwardly extending, interiorly inclined, threaded sockets arranged in spaced relation on-the inner face thereof and adapted to receive the outermost convolution of said ,spring, the oppositeterminal portions of the said outer split ring being provided with inwardly extending flanges studs,

and means adjustablyconnecting theflanges,

whereby the said outer ring may be adjusted circumferentially to cause a proper seating of the tire and also to adjust the said threaded sockets into alinement with thesaid rigid studs.

In testimony whereof afiix my in presence of two witnesses.

MOYLAND E. COURTNEY. Witnesses Coorne, JONES, J W. PERKINS.
